Successively the projection 361 comes into contact with a cam part 382 and thereby the movable vane flap 21 is rotated to the position of closure from the position to which it has been turned at the prescribe angle. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a winning device for a pachinko machine including a movable wing piece that can be rotated to an open position where a game ball to be thrown into a game area can enter and a closed position where the game ball cannot enter.

  In a pachinko machine, when a game ball that has been driven into the game area wins the start winning opening, the movable wing piece of the accessory placed almost in the center of the game area cannot accept the game ball. When the game ball is turned to the open position in the almost horizontal state that can be received from the closed position in the almost vertical state, and the received game ball wins the V prize opening provided in the accessory, it is advantageous for the player. Game rights are generated.

Usually, a solenoid having a plunger that moves straight when energized is used as a power source for opening and closing the movable blade piece. The solenoid is energized and the plunger is sucked from the projecting position to the retracted position to rotate the movable blade piece from the closed position to the open position via a connecting lever that can rotate integrally with the movable blade piece. When energization is stopped, the plunger is returned to the protruding position by the biasing force of the spring, and the movable blade piece is held at the closed position by the biasing force of the spring.
JP 2001-327714 A

  However, in the winning device of the pachinko machine as described in Patent Document 1, the plunger of the solenoid is connected to a connecting lever that rotates integrally with the movable wing piece, so that the connecting point between the plunger and the connecting lever However, the farther away from the rotation center of the movable blade piece, the movable blade piece can be rotated with a lighter force. On the other hand, the movable blade piece can be rotated by a necessary angle (angle between the open position and the closed position). In order to make it move, the operating stroke of the connecting point becomes long, and a spring and solenoid having a long operating stroke must be used. In addition, if the connecting point is close to the center of rotation of the movable wing piece, the movable wing piece can be rotated at the required angle with a short operation stroke of the plunger, but on the other hand, the movable wing piece is now required with a large force. Since the angle must be rotated, a spring with a large biasing force and a solenoid with a high output must be used.

  The present invention has been made in view of the above-described problems, and provides a winning device for a pachinko machine in which a movable blade piece can be efficiently rotated at a necessary angle by a small spring and a solenoid. With the goal.

According to the present invention, the above problem is solved as follows.
(1) A movable wing piece is provided in a game area into which a game ball is to be driven, which is rotatable to an open position in a substantially horizontal state where the game ball can enter by an opening / closing mechanism and a closed position in a standing state where the game ball cannot enter In the winning device of the pachinko machine, the opening / closing mechanism may be a cam lever that can rotate integrally with the movable blade piece around the first support shaft, and a suction operation is performed in one direction when turned on, and the other by a biasing force of a spring when turned off. A solenoid having a plunger that moves in a direction, and rotates around a second spindle in conjunction with a suction operation in one direction of the plunger when the solenoid is turned on, and the movable blade piece is closed by way of the cam lever. To the open position, and when the solenoid is turned off, the plunger is rotated around the second support shaft in conjunction with the operation in the other direction, and the movable blade piece is opened via the cam lever. A relay link that rotates to a closed position, and the relay link is in a position spaced a predetermined amount in the centrifugal direction from the second support shaft and abuts on a first actuated portion provided on the cam lever. Accordingly, the cam lever is located at a position spaced apart from the first action portion in the centrifugal direction from the second support shaft, and the first action portion capable of transmitting the rotation to the movable blade piece via the cam lever. A second acting part capable of transmitting the rotation to the movable blade piece via the cam lever by contacting a second acting part provided at a position different from the first acting part. When the movable wing piece is rotated from the open position to the closed position, the first acting portion abuts on the first acting portion when the relay link is initially rotated, so that the movable wing piece is opened. To a predetermined angle toward the closed position Then by the second acting portion is brought into contact with the second action target portion is rotated to a closed position from a position a predetermined angle rotates the movable wing.

(2) In the above item (1), the second action portion is gradually separated from the first support shaft when the relay link rotates in a direction to rotate the movable blade piece toward the closed position. In this way, the second acting part is slidably contacted.

(3) In the above item (1) or (2), when the movable blade piece is in the closed position, the point of contact of the second acting part with the second acting part is the acting point. And a straight line connecting the center of the second support shaft are substantially perpendicular to a straight line connecting the operating point and the center of the first support shaft.

According to the present invention, the following effects can be achieved.
According to the first aspect of the present invention, the cam lever is rotated by the first action portion having a short action distance from the second support shaft when turning in the closing direction from the substantially horizontal open position requiring a large force. Therefore, the movable blade piece can be rotated with a light force. In addition, from the position where the movable blade piece is rotated by a predetermined angle from the open position, the movable blade piece is largely rotated by the second action portion whose action distance from the second support shaft is longer than that of the first action portion. It can be rotated to a position. Thus, the movable blade piece can be efficiently rotated from the open position to the closed position with a spring having a small urging force. Further, since the urging force acting on the plunger is reduced, a small solenoid can be used.

  According to the second aspect of the present invention, as the movable blade piece approaches the closed position, the closing speed of the movable blade piece can be gradually reduced to reliably stop at the closed position.

  According to the third aspect of the invention, when the movable blade piece is in the closed position, the movable blade piece can be reliably held in the closed position by preventing the movable blade piece from rotating in the opening direction.

  Hereinafter, an embodiment according to the present invention will be described with reference to the drawings. FIG. 1 is a front view of a pachinko machine 1 to which the present invention is applied. In the following description, the front side of the drawing in FIG. 1 is “front or front surface”, the drawing surface is “rear or back surface”, the left side is “left”, and the right side is “right”.

  The pachinko machine 1 has an outer frame 2 installed in a gaming facility, a game board fixed in the outer frame 2 and formed with a circular game area 5 surrounded by an outer guide rail 3 and an inner guide rail 4 on the surface. 6 and a glass frame door 7 that covers the surface of the game board 6 and is supported by the outer frame 2 so as to be opened and closed.

  A game ball stored in a ball supply tray 8 provided below the glass frame door 7 is rotated by an operation handle 9 provided on the lower right side of the glass frame door 7, thereby launching a launching device (not shown). ), Is guided by the outer guide rail 3 and the inner guide rail 4 and is driven into the game area 5, and flows down while coming into contact with a large number of game nails implanted in the game area 5. The game nails are omitted for simplification of the drawing.

  In almost the center of the game area 5, an accessory 20 that can receive a game ball that has been driven into the game area 5 is disposed. At the upper part of the accessory 20, an almost horizontal open position (position shown by an imaginary line in FIG. 1 and a position shown in FIG. 8) and an entrance where a game ball to be driven into the game area 5 can enter the accessory 20 and Left and right movable wing pieces 21 are provided which can be turned to a closed position (a position shown by a solid line in FIG. 1 and a position shown in FIG. 5) in a standing state where it cannot be sphered. Below the accessory 20 in the game area 5, a first start winning port 10 and left and right second start winning ports 11 through which a game ball can win or pass are arranged. Further, at the bottom of the game area 5, there is provided an out port 12 through which game balls that have been thrown into the game area 5 are discharged to the back side of the game board 6.

  2 is a perspective view of the accessory 20 as viewed obliquely from the rear, FIG. 3 is a perspective view of an opening / closing mechanism 30 for opening and closing the movable wing piece 21, and FIG. 4 is an exploded perspective view of the opening / closing mechanism 30. 5 to 8 are explanatory diagrams of the operation of the opening / closing mechanism 30. FIG. Since the left and right opening / closing mechanisms 30 have the same structure, only the opening / closing mechanism 30 that operates the left movable wing piece 21 will be described.

  The accessory 20 includes a box-shaped housing 22 that is fixed to the game area 5 and has an open front surface. The left and right movable wing pieces 21 are pivotally supported on the upper part of the rear side of the housing 22 by a first support shaft 37 that faces in the front-rear direction (horizontal direction). The movable wing piece 21 is opened and closed a predetermined number of times by the opening / closing mechanism 30 when a game ball has entered the first start winning opening 10 or the second starting winning opening 11.

  When the movable wing piece 21 is in the closed position, the swinging end is in an upright state in which the swing end faces obliquely upward, substantially preventing the game ball from entering the accessory 20 and being in the open position. When it becomes almost horizontal, the upper portion of the housing 22 is temporarily opened to increase the probability that a game ball that has been driven into the game area 5 enters the accessory 20, that is, the housing 22. When a game ball entered in the housing 22 wins a V prize opening (not shown) provided in the housing 22, the movable wing piece 21 repeatedly opens and closes a predetermined number of times as a result. A special game state advantageous to the player is generated, and a predetermined game value is given to the player.

  The opening / closing mechanism 30 includes a base plate 31 fixed to the upper portion of the housing 22, a solenoid 32, a connection lever 33 connected to the plunger 41 of the solenoid 32, and a relay link 36 connected to the plunger 41 via the connection lever 33. And a cam lever 38 that can rotate integrally with the movable blade piece 21.

  The solenoid 32 includes a yoke 40 that is fixed to the base plate 31 and a plunger 41 that is supported by the yoke 40 so as to be movable in the left-right direction. The plunger 41 is urged in a protruding direction (rightward in FIGS. 5 to 8) by a conical coil spring 43 interposed between the yoke 40 and the solenoid 32 is turned on to resist the urging force of the coil spring 43. Then, it moves to the left from the projecting position (see FIG. 5), and when it is turned off, it moves from the position that has been attracted and moved by the biasing force of the coil spring 43 to the projecting position.

  The connecting lever 33 is pivotally attached to the plunger 41 by a connecting shaft 39 facing in the front-rear direction, and along the upper surface of the yoke 40 as the plunger 41 moves in the left-right direction when the solenoid 32 is turned on / off. Move left and right.

  The relay link 36 is pivotally supported by the base plate 31 by a second support shaft 35 that faces in the front-rear direction, and is pivotally connected to the connection lever 33 by a connection shaft 34 that faces in the front-rear direction. When the plunger 41 moves in the left-right direction by turning the solenoid 32 on and off, the locking position (see FIG. 5) in an oblique position facing the upper left and the open position in the substantially horizontal position (see FIG. 8) via the connecting lever 33. Is rotated around the second support shaft 35.

  The relay link 36 is separated from the second support shaft 35 in the centrifugal direction by a working distance L3 (see FIG. 6) by contacting an engaging portion 384 forming a first acted portion (described later) of the cam lever 38. A long groove 362 having an opening at the front which forms a first action portion capable of transmitting the rotation to the movable blade piece 21 via the cam lever 38 is provided, and is also longer than the action distance L3 from the second support shaft 35 in the centrifugal direction. At a position apart from the operating distance L4 (see FIG. 6), the cam lever 38 abuts on a cam portion 382 that forms a second operated portion, which will be described later, and the rotation is transmitted to the movable blade piece 21 via the cam lever 38. A shaft-like protrusion 361 that forms a possible second action part is provided so as to protrude forward.

  The cam lever 38 is pivotally supported on the upper portion of the housing 22 so as to swing between the open position and the closed position integrally with the movable blade piece 21 via the first support shaft 37, and the upper arm portion 381 and the lower arm portion 381. The front view having the arm portion 383 is substantially C-shaped. A shaft-like engagement portion 384 that loosely fits in the long groove 362 is projected rearwardly at the rotating end portion of the lower arm portion 383, and the first support shaft 37 is provided at the lower edge of the upper arm portion 381. A cam portion 382 is provided that extends in the centrifugal direction from the vicinity of the protrusion portion, and can contact the protrusion 361. Further, the portion near the tip of the cam portion 382 forms a linear engagement cam portion 382a with which the protrusion 361 can contact from obliquely below when the relay link 36 is in the locked position. Furthermore, a stopper portion 385 that bends substantially downward at a right angle is provided at the tip of the upper arm portion 381.

  As shown in FIG. 5, when the relay lever 36 is in the locked position and the projection 361 is in contact with the engagement cam portion 382a of the cam lever 38, the projection 361 contacts the engagement cam portion 382a. When the point is an action point A, a straight line L1 connecting the action point A and the center of the second support shaft 35 is substantially perpendicular to a straight line L2 connecting the action point A and the center of the first support shaft 37. The positions of the first and second rotary shafts 37 and 35 and the action point A are determined so that Therefore, when the relay link 36 is in the locked position, the force in the opening direction (clockwise in FIG. 5) input from the movable blade piece 21 is directed toward the second support shaft 35 that is the rotation center of the relay link 36. It acts and does not act as a force for rotating the relay link 36. Therefore, the movable blade piece 21 can be reliably held at the closed position via the cam lever 38 by the biasing force of the small coil spring 43. Further, even if a game ball that has been driven into the game area 5 collides with the movable wing piece 21 and acts to move the movable wing piece 21 in the opening direction, the protrusion 361 is engaged with the engagement cam. The movable blade piece 21 does not rattle in the opening direction because it is in contact with the portion 382a. Furthermore, since the urging force of the coil spring 43 can be reduced, the movable blade piece 21 can be reliably moved to the open position by the small output solenoid 32.

Next, the operation of the opening / closing mechanism 30 will be described with reference to FIGS.
As shown in FIG. 5, when the movable blade piece 21 and the cam lever 38 are in the closed position, the solenoid 32 is in an off state, the plunger 41 is held in the protruding position by the biasing force of the coil spring 43, and the relay link 36 is It is held in the locked position via the connecting lever 33. In this state, the protrusion 361 of the relay lever 36 is engaged with the cam portion 382 of the cam lever 38, and the cam lever 38 is prevented from moving from the closed position to the opening direction.

  When the solenoid 32 is turned on and the plunger 41 is attracted against the urging force of the coil spring 43, the operation is transmitted to the relay link 36 via the connecting lever 33. When the relay link 36 is rotated by a predetermined amount in the opening direction (counterclockwise in FIG. 5) from the lock position and the projection 361 is detached from the engagement cam portion 382a as shown in FIG. 6, the movable blade piece 21 and The lock in the opening direction of the cam lever 38 is released. Thereby, the movable blade piece 21 and the cam lever 38 follow the rotation of the relay link 36 in the opening direction due to their own weight and the engagement of the long groove 362 and the engaging portion 284 due to the rotation of the relay link 36. Then, it rotates to the open position shown in FIG. Note that the engaging portion 384 of the cam lever 38 is loosely fitted so as not to engage with the long groove 362 until the protrusion 361 is detached from the engaging cam portion 382a.

  As shown in FIG. 8, when the movable blade piece 21 and the cam lever 38 are rotated to the open position, the solenoid 32 is turned off. As a result, the plunger 41 moves toward the protruding position by the biasing force of the coil spring 43 in the compressed state, and the movement is transmitted to the relay link 36 via the connecting lever 33, and the movable blade piece 21 and the cam lever 38 are in the open position. To the closed position.

  In this case, with the rotation of the relay link 36 by the urging force of the coil spring 43 (clockwise rotation in FIG. 8), first, in the initial rotation operation of the relay link 36, the lower edge of the long groove 362 is By engaging with the engaging portion 384 of the cam lever 38, the movable wing piece 21 passes through the cam lever 38 through the state shown in FIG. 7, and as shown in FIG. Rotates to the moved position. The operation at this time is such that the long groove 362 near the second support shaft 35 engages with the engaging portion 384, so that the movable blade piece 21 can be rotated from the open position to the closing direction with a light force. it can.

  Subsequently, when the movable wing piece 21 rotates by a predetermined angle, the protrusion 361 at a position farther from the second support shaft 35 than the long groove 362 abuts against the cam portion 382, whereby the relay link 36 moves to the cam lever 38. The amount of rotation transmitted is amplified, and the movable blade piece 21 is largely rotated in the closing direction. In this case, since the protrusion 361 is in sliding contact with the cam portion 382 in the centrifugal direction, the closing speed of the movable blade 21 gradually decreases as the movable blade 21 approaches the closed position, and the protrusion 361 At the point of contact with the stopper portion 385, the movable blade piece 21 and the cam lever 38 are stopped at the closed position. Thereby, the movable blade piece 21 can be efficiently rotated from the open position to the closed position by the biasing force of the small coil spring 43.

Although the embodiment of the present invention has been described above, the following various modifications and changes can be made to the present embodiment without departing from the gist of the present invention.
(I) The plunger 39 of the solenoid 32 is directly connected to the relay link 36.
(Ii) The long groove 362 of the relay link 36 has a protruding shape, and the engaging portion 384 of the cam lever 39 has a cam groove shape in which the protruding long groove 362 is loosely fitted.
